which has greater density 5 kg of lead or 10 kg of aluminum
Pay attention to the terms in the questions! Under normal conditions, 5kg of lead has more density but less mass than 10kg of aluminum.
more mass is 10kg of aluminum, grams is the unit for mass, more mass more grams, density depends on its volume and mass, which you havent provided its volume
lead it has the Atomic Weight of= 207.2
The density of ANY amount of lead is greater than the density of ANY amount of aluminum. So even if we have a tiny speck of lead, and a truckload of Aluminum the lead still has greater density. The density of a substance does not depend on how much of it we have. One drop of water have a density of 1g/cm^3 and an ocean of water have exactly the same density of 1g/cm^3. The only difference is that the drop of water has less mass than the ocean, hence it would be easier to fetch; and the drop also has less volume hence it takes up less space.
